Democratic objections to granting President Donald Trump expanded tariff authority are complicating Senate efforts to pass a bipartisan Russia sanctions bill and may prevent what could otherwise be a unanimous vote supporting Ukraine.

In late July 2026, senators began debating the sanctions legislation, a bill that the late Sen. Lindsey Graham had worked on for over a year. More than 80 senators supported two procedural votes to advance the bill, while 12 opposed it, signaling strong bipartisan backing for Ukraine as it continues to fight the war Russia launched more than four years ago.

However, opposition centers on provisions authorizing the president to impose steep tariffs on major purchasers of Russian oil and gas. Massachusetts Democrat Elizabeth Warren argued that granting Trump such authority risks selective enforcement, similar to his past use of tariffs, and suggested that removing these provisions could secure "virtually unanimous support" in the Senate. Warren is among 11 Senate Democrats opposing the bill due to the tariff language.

Connecticut Democrat Richard Blumenthal, a co-author of the bill, said the latest version narrows the tariff provisions with exceptions for countries reducing Russian gas imports, ensuring European allies would not be targeted. Senators Chris Murphy and Mark Kelly expressed concerns about the tariff authority but emphasized they do not want these issues to derail support for Ukraine.

Kentucky Republican senators also joined opposition to the tariff provisions. Senator Rand Paul described the bill as "essentially a vote for a $500 billion increase in taxes."

Meanwhile, Representative Gregory Meeks indicated openness to working with the Senate on a bipartisan, bicameral product that would impose devastating sanctions on Russia and those fueling its illegal war, potentially building on the Ukraine Support Act passed by the House in June.

The debate highlights tensions within the Senate as lawmakers balance strong support for Ukraine with concerns over expanding presidential tariff powers.
